Title: Improvements in or relating to apparatus for tipping railway wagons
IPC: B65G67/00
Filed: 1919-01-31
Abstract: 142,198. Mitchell, F. G. Jan. 31, 1919. Tipping-apparatus.-Railway wagons are held in place in side-tipping apparatus by means comprising a side support and ropes or chains passing over the wagon top, the means being automatically brought into action as the wagon tips. The wagon :is run on to a carrier a, b pivoted on an horizontal axis c, the carrier being rotated by ropes y passing to a winch 2. A side support d is normally held out of action by weighted bellcrank levers i, and is further controlled by chains m passing over movable guides t and pulleys o to chains of weights s, which come into use successively. The guides t are carried by levers u connected to weights w sliding in guides x. As the carrier a, b rotates to tip the wagon, (1) the increasing pull of the chains m due to the weights s moves the support d into contact with the side of the wagon, and (2) the guides t are lowered relatively to the wagon and allow the chains m to wrap over the top of the wagon, so preventing it from leaving its rails. The winch 2 is motordriven, and the motor is assisted by counterweights 6, 7 acting on a rope 5 wound on the winch drum. The counterweights are sufficient to tip the carrier from its normal position, so that a brake is provided on the winch shaft, this brake being automatically released as the tipping-motor is started. The brake comprises blocks 10<a>, Fig. 6, carried by pivoted arms 11<b> operated by a weight 11 acting through links 11<a> and a bent lever. The brake is normally on, but when the winch motor is started, a solenoid 12 is energized and lifts the weight 11 to release the brake. As the carrier tips right over to the discharging position, the counterweight 6 is arrested by stops 8, so that the weights s are sufficient to start to right the carrier.

Title: Improvements in and relating to valves for fluid pressure systems
Inventor: SENIOR WILLIAM JAMES
IPC: F16K17/10
Filed: 1960-01-25
Abstract: 969, 605. Fluid-pressure servomotor systems. AUTOMOTIVE PRODUCTS CO. Ltd. Jan. 25,1961 [Jan. 25, 1960], No. 2700/60. Heading G3P. A pressure relief valve comprises an inlet port 4 normally closed by a valve plunger 8 formed with a through passage 11, so that inlet pressure normally acts on both sides of the plunger which is loaded to the closed position by a light spring 6. A pilot valve, which may be formed by two valve members 22, 27 controls release of fluid from the upper side of the plunger. A needle valve 12 is axially adjustable relative to the bore 11 to vary the flow area of this bore. In operation, when the inlet pressure exceeds a predetermined value, the spring loaded ball valve 22 opens and through a guide member 24, opens the valve member 27 thus allowing leakage from the upper side of the plunger 8 through passages 21 and 31 in a member 32. The pressure drop created across the bore 11 moves the valve plunger to allow flow from the inlet 4 to an outlet passage 7. Flow past the valve plunger 8 may be utilized as a means for regulating the flow past the pilot valve. This is achieved by the passage 31 and port 33 being mounted in a rotatably adjustable rod member 32, the rotation of which varies the outlet port 33 relative to the direction of flow along the passageway 7.
